Gas Cylinder Level Sensor
Gas Cylinder Level Sensor is a device for measuring the residual liquid level of the gas cylinder propane bottle.
We have designed the special Level Sensor suitable for Gas Cylinder with customer needs:
Model: UM13
Integrated Type Gas Cylinder Level Sensor


Gas Cylinder Level Sensor solves the problem of how to measure the remaining liquid level in a Propane Bottle.
- In less than 5 seconds, you can figure out the tank’s liquid level or the remaining volume.
- It can connect to your phone via Bluetooth.
- Automatic alarm for liquid level. When the gas in the propane bottle is nearly used up, the gas cylinder level sensor will automatically alarm.
- It can also upload liquid level information to the Internet. Convenient management of LPG operators, increase user stickiness.

How to upload your Gas Cylinder Level Information to the Internet
The Remote Terminal Unit for Gas Cylinder is an advanced wireless transmission Gateway (WIFI+Bluetooth Gateway). It connects with the Gas Cylinder Level Sensor through Bluetooth and transmits the liquid level data to the Internet through WIFI.
FAQ
Gas Cylinder Level Sensor can only be installed at bottom center of the tank.
Since the ultrasonic wave is propagated vertically, the sensor can only be installed at the bottom center of the tank. If installed on the side where there is liquid, the measured reading is the diameter of the tank; If installed at the top, there is no reading.
A small amount of coupling agent needs to be applied before each sensor installation. The purpose of the coupling agent is to prevent air between the sensor and the tank wall, since air will prevent the transmission of ultrasonic waves.
You’ll need a smartphone (ios or Android) and download SMART TANKS /EchoCheck app.
The sensor uses Bluetooth broadcast mode to communicate with the smartphone. When using the sensor for the first time, the user needs to turn on Bluetooth and the “SMART TANKS” app, then press the “SYNC” button on the back of the sensor for more than 5 seconds until the new tank information appears on the “SMART TANKS” app interface.
Each sensor can connect to multiple phones simultaneously.
Gas Cylinder Level Sensor can be applied to the following cylinders :5kg, 10kg, 15kg, 48kg, 50kg, 20lb, 30lb, 40lb, 100lb.
